Forestry Machinery
Highest performance in the most adverse conditions
Forestry machines have to perform to their full potential on the most difficult terrain in the toughest conditions. The operator's handling must be highly flexible and precise. Large load changes due to lifting and loading operations require maximum dynamics for the hydraulic control system. Speed, high control quality and consistent performance even under continuous stress are required here. For years, customers have benefited from these advantages of Thomas pilot valves and use them in the piloting of their hydraulic systems on harvesters and forwarders.
